Patent number: 7787029Abstract: An imaging apparatus comprises an optical magnification changing mechanism which optically changes a magnification of an image, and an electronic magnification changing mechanism which reduces or expands a magnification with respect to image data by signal processing, the imaging apparatus providing a magnification-changed image according to a predetermined magnification based on the optical magnification changing mechanism and the electronic magnification changing mechanism. The optical magnification changing mechanism has at least two magnifications W and T (W<T) which are discrete each other, and has a switching mechanism which, when a predetermined magnification M (W<M<T) has been set, switches an image obtained by the magnification W and an expanding conversion using the electronic magnification changing mechanism and an image obtained by the magnification T and a reducing conversion using the electronic magnification changing mechanism.Type: GrantFiled: October 27, 2005Date of Patent: August 31, 2010Assignee: Olympus CorporationInventors: Nobuyuki Watanabe, Fumiyuki Shiratani, Noriyuki Iyama, Shinichi Mihara, Hiroyuki Minakata

Patent number: 7782376Abstract: An imaging method includes a step of setting, when a digital zoom operation mode for enlarging an image imaged by a imaging part of an X-Y address type is selected, a zoom magnification and enlarging the image at the zoom magnification set. The imaging method includes the steps of: setting an imaging range in a vertical direction of the imaging part according to the zoom magnification set in the digital zoom step; outputting a driving signal for scanning the shutter signal and the readout signal to perform exposure in the imaging range set in the imaging range setting step and driving the imaging part; and discarding, when the zoom magnification is changed in the digital zoom step, images imaged by the imaging part before and after the change of the zoom magnification to prevent the images from being used.Type: GrantFiled: October 27, 2005Date of Patent: August 24, 2010Assignee: Sony CorporationInventors: Masato Yoneda, Toshio Yamada
